## Projects
### Kiban
A durable LSM-tree storage engine exploring WALs, memtables, SSTables, compaction, and crash recovery from first principles.
- Languages: Rust
- Source: https://github.com/aetosdios27/kiban
- Page: https://aetosdios.xyz/playground/kiban
An embedded LSM-tree storage engine in Rust. Single node. Zero dependencies. Byte keys, byte values, sorted.
Writes go to a write-ahead log, then to an in-memory memtable. Flushes produce sorted SSTables. Compaction merges SSTables and drops versions that no active snapshot can observe. Reads check sources from newest to oldest; sequence numbers order everything.
Benchmarks (from the project's README):

### Kurogane
A from-scratch Rust implementation of Raft behind a replicated in-memory key/value state machine, now feature-frozen.
- Languages: Rust
- Source: https://github.com/aetosdios27/kurogane
- Page: https://aetosdios.xyz/playground/kurogane
Kurogane is a from-scratch Rust implementation of Raft and a replicated in-memory key/value state machine. It was built transport-free deterministic core first, then controlled simulation, and only later networking, persistence, and client-facing behavior — not an imported Raft library and not aimed at being production-ready today.
### Styx
A from-scratch BitTorrent engine in Rust with peer wire, trackers, DHT, magnets, verified storage, and seeding.
- Languages: Rust, TypeScript, CSS, Python, HTML
- Source: https://github.com/aetosdios27/styx
- Page: https://aetosdios.xyz/playground/styx
A BitTorrent client written in Rust, built around strict protocol handling, verified storage, and private-by-default runtime identity.
Styx is not a wrapper around an existing torrent engine. The core protocol, tracker, disk, peer policy, runtime, CLI, and desktop shell are implemented in this repository.
### Scribe
Publishing SDK that turns Markdown, MDX, and JSX into publication-grade technical articles on your own React/Next.js/Vite site.
- Languages: TypeScript, JavaScript, Rust, CSS, MDX, HTML
- Source: https://github.com/aetosdios27/scribe
- Site: https://scribeit.dev
- Page: https://aetosdios.xyz/playground/scribe
Scribe is an open-source publishing SDK that turns ordinary Markdown, MDX, semantic HTML, and JSX into beautiful technical articles on websites you already own.
Just write. Scribe handles the rest.
Scribe is for developers who already own a React website built with Next.js or Vite and want publication-grade typography, code, tables, banners, callouts, figures, responsive behavior, and accessibility without assembling a publishing design system themselves. It transforms semantic article content at build time and renders it through a small React component map plus scoped CSS.
### WebNotes
A local-first knowledge system with structured editing, bidirectional links, native desktop performance, and sync.
- Languages: TypeScript, Rust, CSS, Shell, JavaScript, PowerShell
- Source: https://github.com/aetosdios27/webnotes
- Site: https://web-notes-lyart.vercel.app
- Page: https://aetosdios.xyz/playground/webnotes
The missing link between Apple Notes and Obsidian.
WebNotes is a high-performance, local-first knowledge base designed to bring the polish of macOS-native tools to Windows and Linux, without sacrificing the power features developers need.
It runs on Tauri (Rust) for native performance and Next.js for cloud synchronization.
### Konto
A double-entry accounting engine on PostgreSQL with typed financial primitives, enforced invariants, and agent-safe execution.
- Languages: TypeScript, PLpgSQL, CSS, JavaScript, MDX
- Source: https://github.com/aetosdios27/konto
- Page: https://aetosdios.xyz/playground/konto
Konto is a high-performance, strictly-typed, double-entry accounting ledger system built on PostgreSQL. It ensures financial correctness with a robust core engine and supports integration with autonomous agents.
